BITCH-GATE.

Specification of Letters Patent.

Patented Jan. 10, 1911.

Application filed January 3, 1910, Serial No. 536,068.

To all whom it may concern:

Be it known that I, ADONIRAM J. COLLAR, a citizen of the United States, residing at Yreka, in the county of Siskiyou and State of California, have invented new and useful Improvements in Ditch-Gates, of which the ple form a self-adjusting gate, and a sightmeasuring and controlllng device; and to provide a rellable, relatively inexpensive "ate.

h The invention consists-of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompany- Fig. 2 is a ver- Fig 3' 1s a source as reservoir B or other headwater,

and vertically adjustable in the ditch and close to its intake is a suitable form of closure or gate 2, pivoted at 3, and approximately balanced by a float 4. The ate and float are secured to the ends of a ever or beam 5 which is fulcrumed on an upright 6. s5

In some sections of the country .Where water is carefully used and valuable, it is desirable that 'the consumer may have full knowledge of the quantity of;waterbeing run into the ditch, and to be protected against flooding or unnecessary lack of wa ter at all times, without constantly having to watch the ditch-gate. To provide for and accomplish this desideratum I introduce-at the foot of the gate-way C a suitably constructedcheck-board', preferably in the form of aweir having removable sections 7 insertible'inguides 8 marked with gradations 9.

The operator or consumer having deter mined the .volume of water desired in the ditch, then builds up the weir boards 7 to -obtain.the head, and adjusts the float 4 in a well 10 so as to lift the gate 2 and let in water from the source B; The well 10 is connected to the ditch A by a small branch or conduit 11 across which is placed a flashboard 12, which is made in movable sections substantially like the weir board 7, before mentioned, whereby the vertical height of the flash board may be adjusted, the top of which flash board is raised to a plane-as much higher than that of the weir, as will allow as much water to flow into the ditch as is wanted. The volume ofi' iivater admitted beneath. the gate will back up against the weir and rise above it, under pressure of the mainsource B, eventually falling into the well 10. If it be desired that one inch depth of water shall flow over the, weir, then the flash-board 12 will be set that much higher than the top weir board, and the float 4 will so balance the gate that with a given mean level in the main B, the opening below the gate will just be sufficient to keep the desired amount ofwa'iter' flowing over the weir, and into the we 1.

-In order to make the operation of the gate automatic there is led from the well bottom. a drain ipe 13 having a control ling valve 14, and a downwardly turned end 16.just in the-path of the water discharging over the weir 7. By opening the valve 14 a sufficient amount, water will constantly be dischar ed from the well, the consequence of whic is that if the normal head of water in the main B falls then it will allow the level in the gateway to fall below the top ofthc flash-board, and the pipe 13 will drain water from the Well 10, thus lowering the float 4, and simultaneousl lifting the gate 2, thereby permitting a arger volume of water to pass into the gateway. Inversely, if the head-water in main B rises, more water will pass under the gate and over the flash-board 12, in quantities larger than the adjustable drain valve '14 is set to 'run off, and as the level in the well and gateway increases, the float will rise, and the gate .2 will be lowered until the normal condition of levels has again returned. By leading the drain 13. into the ditch and in the discharge water a double advantage is obtained.

First, the drain is discharged near the well bottom,.' and secolid=the suction produced by erated b I claim and desireto secure by letters Patpended counterweight, a centrally fulerumed whichthe weight is suspended, a measuring and which affords a means always indicating at sight the height and width of the stream of water passing into the ditch. Preferably the check or weir board is centrally divided thus delivering two separate, parallel streams into the ditch which I find by experience results in" causing a less agitated current in the ditch. Y

Attention is particularly drawn to Fig. 1 in which is shown the connecting assage 11 between the well 10 and its supp y or wellhead C, in which the gate is controlled. The relative levels of water in the system are as follows: The highest. level is in the main B, the next level is in the portion C of the ditch behind the gate, and 111 front of the adjustable weir 7 the lowest level being in the tail-race or ditch A. Since the gate is opa fluctuation of level in the well. 10, the rain 13 must necessarily discharge at a level lower than that in the section G or well 10, and this is done by leading it to the ditchA.- if

Having thus described my invention, What out is' A l. A ditch gate pivotally imounted, a susbeam to the opposite ends of which said gate and weight are eonn'ected, a well in weir located in the gatewaybelow the gate, and an adjustable flash-board over which water flows into the well from the gateway, and a drain from the well. -.2. In combination with a water supply, and a branch, an adjustable controlling gate operable in a gateway, means whereby said gate is normally balanced, and a measuring, chcck-l'mard below said gate.

3. A control for ditches and the like, said control consisting of a main gate, a weir, an interposed well and float, connections between the float and the main gate, and a limited discharge from the well.

4. A control for ditches and the like, said over the weir:

control including a main gate, a weir, a float containing .well connected with the water- I space above the weir, a flash-board in said connecting passa e, and a lever connecting the main gate an .the float.

5. A control for ditches and the like, said,

device including a main gate, a weir, a float containing w ll. a lever connecting the float aiidgate, a channel between the Well and the wauarspace above the weir, and an adlnsiable flash-board in said channel. 1

device including a main gate, a weir," a float containing well, a lever connecting the float and gate, a channel between the Well and the water-space above the weir, an adjustable flash-board in said channel, a drain assage.

connected with the float chamber, an a controlling valve in said passage.

8. A control for ditches and the like, said. device including a main gate, a Weir, and means whereby the.'flow --of water is controlled by the fluctuations of its flow.

9. A control for ditches and the like, said control including a main gate, a weir, a floatcontaining chamber connected with the water-spacebetween the gate. and weir, a

lever connection between the float and gate, and means to regulate the level of water in the float well. I

10. A control for ditches and the like, said control including main gate, a weir, a floatcontaining cham er connected with the :water-space between the gate and weir, a

lever connection between the float and gate,- meansto regulate the-level of water in the float -,W3ll, and a visible gage for the flow 11'. 'Anautomatic control for the flow of water, said control including a float-actuated head gate, and a delivery weir below said gate, a channel and flash-board between the float well and the water-space above the-weir, amll an adjustable discharge from the float we 1..

12. An automatic control for the flow of water, said control including a float-actuated head gate, and \a delivery Weir below said gate, a channel and flash-board between the float well and the water-space above the weir, and an adjustable'discharge from the float well, said discharge leading into the outfall from the weir.

In testimony whereof I- have hereunto set my hand in the presence of two suhscribim; witnesses.
